What is saturation in qualitative research?
What is saturation in sampling? Saturation can be simply defined as data satisfaction. It is when the researcher reaches a point where no new information is obtained from further data. Saturation point determines the sample size in qualitative research as it indicates that adequate data has been collected for a detailed analysis.
What are the advantages of saturation sampling?
In addition, Fontanella et al (2008) add that saturation sampling allows the researcher to take a multifaceted approach in the study by removing the limits to the techniques of data collection, the mode of use, and the type of data collected.
How do you know when you are approaching data saturation?
When the amount of variation in the data is levelling off, and new perspectives and explanations are no longer coming from the data, you may be approaching saturation.
What is theoretical saturation?
Theoretical saturation is the point in grounded theory analysis where collecting and analyzing additional data does not teach you more about your topic. Learn more about theoretical saturation. What is Constant Comparative Method?
What does saturation mean in research?
Saturation means that no additional data are being found whereby the sociologist can develop properties of the category. As he sees similar instances over and over again, the researcher becomes empirically confident that a category is saturated.
Is saturation a sampling technique?
Saturation is applied to purposive (nonprobability) samples, which are commonly used in qualitative research. Saturation is an important concept because it provides an indication of data validity and therefore is often included in criteria to assess the quality of qualitative research.
Why is saturation of data important?
Data saturation is important to achieve. It is reached when there is enough information to replicate the study, when the ability of obtain additional new information has been attained, and when further coding (identification of themes) is no longer feasible.
How do you determine data saturation?
Data saturation is reached when there is enough information to replicate the study when the ability to obtain additional new information has been attained, and when further coding is no longer feasible.
What is the relationship between saturation and sample size?
When used in the broader context, saturation refers to the point in data collection when no additional issues or insights are identified and data begin to repeat so that further data collection is redundant, signifying that an adequate sample size is reached.
How is saturation achieved in qualitative research?
Saturation in qualitative research is when, through the course of interviewing (or observation), you notice the same themes coming out, repeatedly. As you interview more and more participants, you stop finding new themes, ideas, opinions, or patterns.
How does the researcher know that data saturation has occurred?
B Data saturation occurs when the researcher recognizes that he or she has heard themes before in multiple prior interviews.

Abstract
Saturation has attained widespread acceptance as a methodological principle in qualitative research. It is commonly taken to indicate that, on the basis of the data that have been collected or analysed hitherto, further data collection and/or analysis are unnecessary.
Introduction
In broad terms, saturation is used in qualitative research as a criterion for discontinuing data collection and/or analysis. Footnote 1 Its origins lie in grounded theory (Glaser and Strauss 1967 ), but in one form or another it now commands acceptance across a range of approaches to qualitative research.
Conclusion
This paper has offered a critical reflection on the concept of saturation and its use in qualitative research, contributing to the small body of literature that has examined the complexities of the concept and its underlying assumptions.
